The Zaphir block is located in Eastern offshore Tunisia where water depth is less than 100m.
The ZAPHIR block is located within the Pelagian platform. This latter acted as a carbonate platform developed since the cretaceous to tertiary times. Structurally, the block is marked by several grabens (Isis and Jerrafa) and highs related to a fault system trending WNW-ESE and volcanic activities.
Reservoirs and Seals
- The main reservoir in the block is the Cenomanian Isis reefal limestones.
- Secondary reservoirs target are represented by the Aptian Serdj fractured dolomites and Senonian Abiod chalky fractured limestones.
- The Lower Cretaceous siliciclastic levels are additional targets.
- The Albian lower Fahdene black shales constitute the main and mature source rock in the area.
- The Upper Cenomanian-Lower Turonian Bahloul laminated limestones and the Lower Eocene Bou Dabbous limestone can be additional source rocks.
The mainly trap types in the block are structural, including anticlines, fault related traps and tilted blocks. Stratigraphic trap include Reef buildup.
